Mike,
I take it your running 2:1 gear boxes, what size props are you turning?
3's or 4?
Thanks.

Right now I'm running 21X23 3 blade, but think that I'm a little over-proped. I liked my 20x22 4 blade props better. When they turned to swiss cheese in a poorly grounded marina, I got the bigger ones....and have been too lazy or too cheap to get another pair of fours.

Bruce,

I am running the same set up mechanically as Mike, but I have the 4 blade props.

I will get the sizes off them this coming weekend and let you know what they are if you like.

Bruce,
Looked through my files for 4 cylinder Yanmar repowers, prop sizes. Only got 2 31's. Both have Hurth 2 to 1 gears. No flow scans on either boat.

Check with Doc he's got 240 Yanmars also.

Any idea when we are supposed to play that golf date, before April 24?.

Thanks Pete.

Still don't know the exact details and date of the game/luncheon. Will try and find out today.
